Answer 1

Part C:

∆G_rxn = ∆H_rxn - T∆S_rxn

_{​​​​​​}Given: ∆H_rxn = -131 kJ = -131000 J

∆S_rxn = -262 J/K

T = 308 K

∆G_rxn = -131000 - (308 × -262)

∆G_rxn = -131000 + 80696 = -50304 J

∆G_rxn = -50.304 kJ

Part D:

Given: ∆H_rxn = -131 kJ = -131000 J

∆S_rxn = -262 J/K

T = 557 K

∆G_rxn = -131000 - (557 × -262)

∆G_rxn = -131000 + 145934 = 14934 J

∆G_rxn = 14.934 KJ
